Commissioning of the water system (heat source) of the air conditioning system-equipment commissioning
Article overview: Water test operation of surface cooler and spray device in air conditioning unit. Check whether the pressure difference between the inlet pipe pressure and the outlet pipe pressure of the meter cooler is within the normal range and whether there is water leakage; whether the water trap of the meter cooler is installed correctly and whether the discharge is smooth.
Water test operation of the surface cooler and spray device in the air conditioning unit. Check whether the pressure difference between the inlet pipe pressure and the outlet pipe pressure of the meter cooler is within the normal range and whether there is water leakage; whether the water trap of the meter cooler is installed correctly and whether the discharge is unobstructed. Whether the nozzles of the sprinkler device are installed, whether the installation direction is correct and whether the specifications are correct (note the difference between summer and winter); whether the water flow rate of the baffle is normal (when the fan is turned on and the air volume is maximum)
Trial operation of cooling tower. Check whether the rotation direction of the fan is correct, whether the water distribution of the water distributor is uniform, and whether the speed of rotation is appropriate, etc. For cooling water systems with multiple cooling towers in parallel, attention should be paid to the adjustment of the bias flow of cooling water.
Turn on the automatic vent valve at the highest part of the chilled water system and cooling water system of the water system. This automatic vent valve is normally open to drain the water system. Open the manual vent valve of the fan coil one by one to empty the fan coil.
Water system chilled water system water distribution adjustment. The same process pipe and balance valve are not installed in the water system. For branch pipes on each floor, adjust water distribution according to design requirements and actual needs; for branch pipes on the same floor, adjust water distribution according to design requirements and actual needs.
The hot water supply system is mainly the steam heating system debugging
1) Switch the chilled water system to the hot water supply system. It is to close the chilled water inlet and outlet valves of the chiller, and open the inlet and outlet valves of the water vapor exchanger.
2) Notify the steam delivery department to deliver the steam to the steam drum in the air-conditioning machine room.
3) After the sub-steam drum is under pressure, open the bypass valve of the sub-steam drum condensate. After the condensate is drained, close the bypass valve and use a steam trap.
4) Check whether the valves and flanges on the steam pipeline are dripping, leaking or running.
5) Check whether the indicated value of steam pressure is the same as the boiler steam pressure gauge.
6) Check the steam pressure safety valve and do manual steam release test
7) Send steam to the water FAW exchanger, and adjust the pressure reducing valve.
8) Open the condensate bypass valve of the water FAW exchanger, after draining the condensate, close the bypass valve and use a steam trap.
9) Adjust the amount of steam to be supplied according to the hot water temperature of the air conditioner.
